HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 787,132, dated April11, 1905.

application tiletl January 7,1904. Serial No. 138,070-

To all lr/tont if HIM/Q1, concern/r le it known that I, HORACE M.I.-\t.t.n.-\. a citizen of the United States, residing at Shel byville,in the county of Shelby and State of Illinois, have invented certain newand useful Improvements in Ilay-lresses, of which the following is aspeii-ilication.

My present invention relates to improvements in hay-presses, and hasspecial reterence to an improved horse-power press in which a novel andsatisfactory form of selft'eed is employed, my self-teed attachmentbeing so constructed as to have the necessary power and strength to Feedthe hay to the press in heavy teeds,as is desired in two-beat presses.The same, however, can be used in connection with threebeat presses, aswill be hm'einat'ter shown.

Another object of my invention is to provide a straight direct-pullself-feeding mechanism which has power enough to push down the heaviestfeeds of hay that is possible to feed in any press, large or small, thesaid teeding mechanism being operated simultaneously with thecompressing mechanism, so that the hay is fed directly into the hopperin front ol the plunger at the desired time and in uniform bulks.

Another object of my invention is the pro vision of a tripping devicewhich will not allow the teed-arms to be pulled down into the press inthe event the t'ollower does not rebound clear, so that the arms of theself-feed can go to the bottom of the press, the said tripping deviceoperating the self-feed, so as to prevent the same from being forceddown upon the follower to prevent the self-feed from being broken, thistrip device being entirely actuated by the plungcr-actiniting device.

I would have it understood that my improved self-feeding attachment andtripping device can be employed on two-beat presses as well as three-l,eat presses and that the tripping attachment can be used with otherforms of selt-feeders To attain these objects, the invention consists ofnovel features of construction and combination of parts, substantiallyas disclosed herein.

In the accompanying drawings, Figure l is a side elevation of mycomplete hay-press. Fig. .2 is a top plan view thereof. Fig. 3 is anenlarged side elevation of the three-beat and trip mechanism of thepress. Fig. I is a top plan view thereof. Fig. 5 is an enlarged detailview of the feeding mechanism detached from the baling apparatus. Fig.(l is an enlarged detail view of the tripping device for theselt't'ecding mechanism detached.

lxet'erring to the drawings, the numeral l designates the bed of thehay-press, 2 the baling-case at one end ot the same, and 3 the hopper.said hopper being so arranged with respect to and in comnnmieation withthe baling chamber or case as to allow the hay to be properly tedtherein. In the front wall I of the hopper I provide an opening 5, andupon the inner face of said wall, having both of its ends attachedthereto, is an inwardly-curved plate or guide-wall (3. This guide-wallmay be formed integral with the wall of the hopper, but is soconstructed as to provide two substantially parallel slots T, so thatthe feeding-arms 8, carried by the rock-shaft 9, may have their uppertwo point ends It) project into the hopper through said slots and beoperated so as to feed the hay into the baling chamber or case. Thisrock-shaft S) is journaled in the bearings ot' the bracket II and hasupon one end a double crank-arm l2, having pivotally connected thereto alink 13, which has connected to it the returning-spring 'l-l, which isadapted to automatically return the feeding-arms to their uprightposition. Carried upon the opposite end of the rockshatt 9 is a groovedsegment 15, which has mounted therein the operating-chain 16, whichpasses over the gui .lepulley l7 and is connected to a rod .18,adjustably secured to the end of the arm carried by the frame 20. Thisframe consists of the two side pieces 21, which have their inner ends 22pivotally connected to the vertical power-shaft This much of themechanism comprises my self-feeding attachment, and it can be readilyseen that the same can be attached to any form, either a two or threebeat baling-press.

Connected to the upper end of the powershaft is a two-arm casting 2%, towhose ends are secured the power-pole 25 and bracing-rod 26,respectively. By this means h orsepower is transmitted to thepower-shaft, and consequently to the triple-arm trip-lever 27, the samebeing rigidly secured to and revoluble with the power-shaft 23. In theouter end of each one of the arms of this trip-lever is mounted anantifriction-roller 28.

Connected to the forward end of the bed of the hay-press is a yoke 29,whose upper end surrounds and forms one of the upper bearings for thepower-shaft 23, an adjustable strengthening-rod 29 being secured to theupper end of said yoke and to the yoke 30, secured to the forwardportion of the balingcasing.

Secured to the bed and rear of the powershaft 23 is a vertical axle 31and a circular disk 32, whose upper face is inclined or beveled towardthe front of the bed, and rotatably mounted upon said shaft and providedwith a corresponding inclined disk 33 is a guide-arm 34, provided uponits free end with the upwardly-extending guide 35. Surrounding the saidaxle above the disk of the arm is a Washer 36, and pivotally mountedabove said Washer is a disk 37, carrying a stop-lug 38 and a curved arm39, provided with a'vertical sleeve 40, to which is pivotally secured apair of curved arms 41, whose outer free ends are pivotally securedtothe pin 42 of the projection 43, carried upon the outer end of thepitman 44. Carried upon the extreme other end 45 of the pitman is theplunger 46, which is adapted to slidably operate within thebaling-chamber. In order to properly return the pitman after thecompression of the bundle of hay, I provide a spring47, which isconnected to the pitman intermediate of its length and to the eyed lug48.

Thus far I have described the compressing mechanism and the automaticfeeding mechanism; but in order to allow the feeding-arms to at alltimes be free of the plunger, so as not to be injured thereby, I providea frame 49, which is pivotally secured at 50 to the outer portion of theframe 20, to which the feeding mechanism is connected. This frame isprovided upon its upper face withalug51, to which is secured a spring52, whose other end is secured to a lug 53, rigidly secured upon thefeed-operating frame. From this construction it will be seen that whileone of the triparms is pushing the plunger forward and compressing abundle of hay the arm forward thereof is about to contact the frame 49and slightly pull the automatic feed -operating frame rearward, and assoon as the first-mentioned arm has released the pitman the pitman andplunger are returned, and the feeding-arms of the feeding mechanism areoperated to feed a bundle of hay into the hopper in front of theplunger, this feeding operation being continued until the arm which hasjust been released from the end of the pitman is in contact with thecurved arm 41 and the pitman is about to be pushed forward by saidcontact. At this juncture the trip-arm which is in engagement with thespring-actuated frame 49 is in such a position that the pressure thereonmoves the spring-actuated frame 49 to one side, and thereby releases thefeed actuated frame 20 and allows the spring connected to the rock-shaftof the feed-arms to return said feed-arms to their upright position, sothat the next action of the pitman will properly compress the bundle ofhay just fed into the compressing-chamber.

In order that the feed mechanism will not be broken in the event thatthe follower or plunger does not rebound clear of the lever or to itsfarthest rearward point, I provide a chain 54, which has one endconnected to the lug 55, carried upon the lower front wall of thespring-actuated frame 49, and the other end of said chain is connectedto the doubleended trip-lever 56,which is pivotally mounted intermediateof its length to the plate 57, carried upon the bed 1 of the press. Uponthe other end of this trip-lever 1 provide an upwardly-projecting lug58, while a trippingplate 59 is carried upon the inner face of thepitman, another chain 59 being connected at the opposite end of saidtrip-lever and to the lug 60, secured upon the bed of the press.

The trip mechanism for releasing the feeding mechanism and providing ameans Whereby the feeders are released when the plunger sticks in thehaling-chamber is the gist of my invention and resides in the feeder 8,chain 16, arm 19, frame 20, and the small trip-frame 49, combined withthe tripping-lever 27, any one of whose members While in operation is inengagement with the frame 49. Should the feeder be in danger, thetrip-plate 59 engages or contacts the lugs 58, holding the lever 56stationary, the said lever holding the chain 54, which in turn holds theframe 49, causing the disengaging of the same from one of the levers 27,and thus releasing the frame 20, arm 19, and chain 16, so that thespring 14 is free to operate the feed and lift the same out of thehopper, and consequently out of the path of the pitmans plunger. Thisreleasing operation takes place as the pitman and plunger is movingtoward the hopper.

The automatically-operated self-feeding attachment is constructed so asto operate just after the return of the plunger, so as to feed the haywithin the baling-chamber and be itself returned out of the way of theplunger before the plunger compresses the hay just fed, the said feedmechanism being combined with an automatic trip, which is arranged to beoperated by the pitman and to return the feed mechanism to itsinoperative position in case the pitman and plunger are not returned tothe proper position. In this Way the hay is at all times properly fed tothe compressing-chamber and the feeding device is pre- IIO vented frombeing broken by the plunger or compressing mechanism.

All of the mechanism combined in this Inachine are controlled primarilyand automatically by the trip-lever, which in this case is a three-armedmember; but it can be constructed with a two-armed member, theconstruction herein shown being not intended to limit me to thethree-armed trip-lever.
